Low-grade cement raw material grinding aid as well as preparation method and application thereof
The invention discloses a low-grade cement raw material grinding aid as well as a preparation method and application thereof. The low-grade cement raw material grinding aid is prepared from triethanolamine, triisopropanolamine, sodium silicate, acetone, sodium polyacrylate, potassium xanthate and deionized water. According to the invention, the distribution of CaO and Si O2 in the raw material can be effectively improved, after the prepared raw material is calcined, the content of free CaO in the clinker is reduced, the compressive strength of cement is improved, and by improving the burnability of the raw material and the cement strength of the clinker, an idea is provided for further improving the utilization rate of the low-quality raw material as the cement raw material, improving the cement performance and expanding the cement variety production. When the grinding aid is used in a ball mill, screening and synergistic effects of the grinding aid can be carried out in the aspects of reducing the hardness of difficult-to-grind substances in raw materials, improving adhesion caused by fine particle aggregation, improving the dispersion effect between particles and the like, and the grinding effect of the raw materials is effectively improved.
一种低品位水泥生料助磨剂、制备方法及应用，由三乙醇胺、三异丙醇胺、硅酸钠、丙酮、聚丙烯酸钠、黄原酸钾和去离子水组成。能有效改善生料中CaO与Si O2的分布，所配置生料煅烧后，熟料中游离CaO含量降低，水泥抗压强度提升，通过提高生料易烧性和熟料水泥强度，为进一步提升低品质原料作为水泥原料的利用率，提高水泥性能，扩大水泥品种生产，提供了思路。本发明在球磨机中使用时能够降低原料中难磨物质的硬度与改善细颗粒聚集造成的粘附以及提升颗粒之间的分散效果等方面进行助磨剂的筛选与协同作用，有效改善生料的粉磨效果。
